• TITLE: Conocephalum conicum (L.) Dumort: A Case of Unique Reproductive Biology

  AUTHORS: Madhu Bhagat, Anil Sharma, Anima Langer

  KEYWORDS: Reproductive Biology; Liverworts; Dioecious; Sporophyte; Spore-Elater Ratio

  JOURNAL NAME: American Journal of Plant Sciences, Vol.3 No.8, August 31, 2012

  ABSTRACT: This paper reports spore-elater ratio per capsule in three populations of Conocephalum conicum collected from different regions of Jammu and Kashmir (Doda, Ladakh and Bhaderwah). Spore-elater ratio came out to be 0.40-0.43:1, far less than expected for Marchantialian taxa. The ratios thus obtained were compared with that present in herbarium specimen collected in 1958 from Kyushu. The ratios have remained constant since many decades, thereby indicating that the sex-ual reproduction has lesser role to play in the propagation of this species.
